Huawei V2 and V3 Server RAID Controller Card User Guide 36

This document describes the appearances and features of the redundant array of independent disks (RAID) controller cards, how to configure properties for the RAID controller cards, and how to install drivers. The RAID controller cards include the LSI SAS2208, LSI SAS2308, LSI SAS3008, LSI SAS3108, LSI SoftRAID, PM8060, and PM8068.

Creating RAID 0

Creating RAID 0


The PM8060 supports SAS/SATA HDDs and SSDs. Hard drives in one RAID array must be of the same type, but can have different capacities or be provided by different vendors.



  1. Back up data on hard drives and access the Configuration Utility main screen. For details, see Logging In to the Configuration Utility.
  2. Initialize member drives.

    Before an array is created, if the predetermined hard drive contains partition information or is totally used for creating another array, the hard drive is gray and cannot be selected. Initialization is required if you want to use this hard drive as a member drive of the new array.

    1. Select Logical Device Configuration and press Enter.

      The array configuration main screen is displayed, as shown in Figure 10-12.

      Figure 10-12 Array configuration main menu

    2. Select Initialize Drives and press Enter.

      The screen lists all hard drives, as shown in Figure 10-13.

      Figure 10-13 Hard drive list

    3. In the Select drives for initialization area, select the hard drives to be initialized by pressing the space or Insert button.

      The selected hard drives are displayed in the Selected Drives area, as shown in Figure 10-14.

      To cancel the selected hard drives, you can press Del.

      Figure 10-14 Selecting the hard drives to be initialized

    4. Press Enter.

      A confirmation dialog box is displayed.

      Initialization clears the data on the RAID member drives. Be cautious to perform this operation.

    5. Enter Y.

      The Initialization begins and lasts for about 10 seconds.

    6. Press any key to return to the screen shown in Figure 10-12.

  3. Select the member drives.

    1. Select Create Array and press Enter.

      The hard drive list is displayed.

    2. In the Select drives to create Array area, select the hard drives to be added to the array by pressing the space or Insert button.

      The selected hard drives are displayed in the Selected Drives area, as shown in Figure 10-15.

      Figure 10-15 Select the member drives.

  4. Configure array properties.

    1. Press Enter.

      Enter the array configuration screen, as shown in Figure 10-16. The description about parameters on the screen is given in Table 10-6.

      Figure 10-16 Array properties screen
      Table 10-6 Parameter description



      Array Type

      Indicates the current RAID level.

      Array Label

      Indicates the array name.

      Array Size

      Indicates the array capacity.


      This parameter is set to the maximum value by default. If multiple logical drives are to be created, manually set the array size.

      Stripe Size

      Indicates the stripe size (64 KB, 128 KB, 256 KB, 512 KB, or 1024 KB).

      When Array Type is RAID 1 or Volume, the value of this parameter cannot be changed.

      Read Caching

      Enables or disables the cache function.

      Write Caching

      Indicates the write cache policy, which can be set as follows:

      • Enable Always: RAID write cache is still enabled in case of no capacitor protection, and data loss may be caused if a power failure occurs.

      Exercise caution when selecting Enable Always.

      • Enable With Backup Unit: RAID write cache is disabled in case of no capacitor protection or in case that capacitor protection is not ready. This setting is recommended.
      • Disable: RAID write cache is always disabled.

      Create RAID via

      Specifies the actions performed after creating an array.

      • Quick Init and Skip Init can be performed for RAID 0, 1, and Volume. Quick Init allows you to quickly initialize the array data, and Skip Init allows you to recover the array and to set the RAID properties among different hard drives without clearing the data.
      • Besides Quick Init and Skip Init, Build, Verify, and Clear can also be performed for arrays with a redundancy function and allow you to initialize and clear the array data.
    2. Select RAID 0.
    3. Configure the other array parameters according to Table 10-6.
    4. Select Done and press Enter.

      The system creates an array and performs the operations defined in Create RAID via.

      After the creation is complete, the array management screen is displayed.

  5. (Optional) Create multiple logical drives.

    • This operation can be performed only when the array size is smaller than the maximum value.
    • A maximum of 64 logical drives can be created for each array.
    1. After the array is created, repeat 3 to 4, as shown in Figure 10-12.

      You can create multiple logical drives based on the actual situation.

  6. Check the configuration result.

    1. On the screen shown in Figure 10-12, select Manage Array and press Enter.

      The array list is displayed, as shown in Figure 10-17.

      Figure 10-17 Array list
    2. Select an array by pressing and and then Enter.

      The configuration information about the array is displayed.
